But be sure to finish all the medicine.
Sore throats caused by viral illnesses usually last 4 or 5 days. A sore throat caused by Strep will start feeling better soon after being treated with antibiotics. After a child has been taking medicine for strep for 24 hours, strep is no longer contagious. Your child can then return to day care or school if his fever is gone and he's feeling better. Your child must take all of the antibiotic even if he is feeling better.
